rate law |
r = k[A]^x[B]^y where A and B are the reactants |
|
|
Order of reaction |
x + y (sum of the order of reactants) |
|
|
0 order |
When [R] vs t is linear |
|
|
1st Order |
When ln[R] vs t is linear |
|
|
2nd order |

|
Integrated Rate Law 0 order |
[R] = -kt + [R]0 |
|
|
Integrated Rate Law 1st order |
ln[R]/[R]0 = -kt |
|
|
Integrated Rate Law 2nd order |
1/[R] = kt + 1/[R]0 |
|
|
Half life 0 order |
t1/2 = [R]0/2k |
|
|
Half life 1st order |
t1/2 = 0.693/k |
|
|
Half life 2nd order |
t1/2 = 1/k[R]0 |
|
|
Catalyst |
A species that speeds up a rxn by finding an alternative pathway. This species is not consumed in the rxn. |
|
|
Inhibitor |
A species that slows down a rxn. Not consumed. |
|
|
Types of catalysts |
1. Heterogeneous: different states of matter ex: catalytic converter 2. Homogeneous: same state of matter ex: I- in elephant toothpaste, blood + H2O2 --> H2O + O2 + blood, enzymes (-ase) |
|
|
ln(k1/k2) |
= Ea/R(1/T2 - 1/T1) R = 8.31 J/molk T = Kelvin k = rate constant |
